Abstract: An electric toothbrush comprises two main casings, a battery/motor casing and a brush drive casing, both casings being made of plastics material and one casing telescopically fitting over the other. The casing contains a battery, a motor and a motor shaft which carries the first gear of a reduction gear set which also comprises gears which drive a motor gear output shaft carrying a male coupling. The brush drive casing carries a brush head further reduction gearing and a brush drive shaft which carries a female coupling. When the couplings are mated telescopically, the male and female couplings connect so as to complete the drive to the toothbrush head. Preferably the toothbrush head is arranged to be driven in alternate directions, i.e., so as to have a reciprocal motion.

Abstract: Presented is a fluid drive motor that may be attached to a conventional garden hose, for instance, to effect reciprocating motion of a drive shaft that may be connected to a utilitarian device, such as a scrub brush. The fluid drive motor is provided with a piston assembly that responds to the pressure of the fluid to translate the piston assembly from one position to another and in so doing imposes rotational reciprocation on a drive shaft that extends out of the motor block of the fluid drive motor. The reciprocating characteristics of the piston assembly are controlled by the imposition of fluid pressure, and the imposition of fluid pressure is controlled by a valve assembly cooperating with a reciprocable magnetic bar to channel fluid under pressure alternately to opposite ends of the piston assembly.

Abstract: An electric toothbrush has a reciprocating connecting rod in a brush member. The brush member is constructed as a brush head at its front end and has there two rows of rotatable bristle holders which each engage with a cam in a transversely running groove in the connecting rod. Rectilinear movement of the connecting rod leads to an alternating rotating movement of the bristle holders.
